I just assembled a new computer: amd 2200g ($90) + MSI B450M MORTAR ($90) + Intel 512GB SSD M.2 ($68) + 4 x 16G 2666 memory (4 x $72).

I installed the debian testing system. After the installation, X hung at starting up. But after installing amdgpu driver by following this tutorial: https://wiki.debian.org/How%20to%20install%20official%20AMDG... , it works like a charming now.

I had to double check your price on the SSD. When did SSDs get so cheap??

That was my reaction when I looked again.

You can get a 1TB WD Black nvme m2 ssd for less than half the equiv a year ago, bonkers.

Just this past month every local semi-tech store (think Staples, Best Buy, etc) had sales on SSD's that were nuts. I picked up a stack of 120 Gb HP drives for ~$20 each, and the 256's were not even $10 more. It let me put back in to use a bunch of good-except-for-dog-slow-spinning-rust systems I had lying around. Not complaining!

QLC being intro'd, iirc, was the most recent inflection point.

(background reading: https://en.wikipedia.org/wiki/Multi-level_cell)

SSDs were held up in prices artificially for a while related to the memory price inflation that happened throughout 2018 and some of 2017. QLC was mentioned but prices are down across the board and everything in consumer land is down sharply YoY from that period (50%+ discount is fair). I’d expect some price increases coming up due to investor pressure for revenue.

What about SSD reliability? Did it improve in the last year or so?

QLC literally drops write endurance by an order of magnitude but most consumers won’t be hit by it. Most of the performance is from the SLC cache and it tanks once it gets full or with sustained usage. The bet is that won’t matter for 99% of users but most of HN is not that 99% so caution must be exercised when buying these SSDs.

Do you happen to know if cpu and case fan controls work on Debian on your machine? I have a server with a very similar setup, but cannot control the fans.

  No sensors found!

I saw this a few days ago. I dont think it will fix your specific issue but if you're wanting to monitors temps there's this: https://www.reddit.com/r/Amd/comments/c2lgeg/linux_monitorin...

I've not tested with my 2200g yet.

I had to install the out of tree version of it87 to get fan control working on my ASUS Prime X370-Pro.

Unfortunately, the driver was abandoned last year, but copies of the code are still around on github.

The sensors command returns the following info:

    $ sensors
    amdgpu-pci-3800
    Adapter: PCI adapter
    vddgfx:           N/A  
    vddnb:            N/A  
    temp1:        +36.0°C  (crit = +80.0°C, hyst =  +0.0°C)
    
    k10temp-pci-00c3
    Adapter: PCI adapter
    Tdie:         +36.5°C  (high = +70.0°C)
    Tctl:         +36.5°C

I don't know how to detect fan temperatures.

Why a B450 board over an older cheaper A320 board if you're using a 2200g?

Edit: NM, probably RAM...

Yes, one reason. The other is the board supports two m.2 slots.

Wow - nice combination. I am going with an ASUS B450 prime myself.
